Member Data Documentation

data

string AsyncDataLoadTask::data

the raw file contents, as a string (nil if the file could not be read).

The callbacks passed to loadData and loadTextData receive the data already decoded, so they never touch this property. It is what makes the polling pattern usable: wait until task.finished, then read task.data and decode it yourself — see Custom Data I/O.
